A MonoBlade is a normal weapon with a monomolecular edge.  It does an extra die of damage (times your Linear Scale) and has an armor divisor of ten.  This bonus only applies to cutting damages, and is ignored when trying for an impaling 
thrust.

Most knives and swords are readily available in MonoBlade form for a reasonable cost; Halberds, Axes, and other weapons
are more unusual and thus are harder to come by in MonoBlade form.

[MonoBlade]s cannot coexist as [VibroBlade]s.  It is not possible.

Most Knives and Swords are readily available in Monowire versions. Halberds and many axes and polearm versions may be available or manufacturable at a much higher cost.
